  17 # Ensure `make dist' fails when help2man replacement man pages are created.
  18 #
  19 # The assumption here is the following: if the developer uses help2man to
  20 # generate man pages from --help output, then these man pages may not be
  21 # stored in VCS.  However, they should be distributed, so that the end user
  22 # that receives the tarball doesn't have to install help2man.  If they are
  23 # not distributed, then the developer should make help2man a prerequisite
  24 # to building the package from a tarball, e.g., with a configure check for
  25 # help2man that errors out if it is unavailable.  In both cases it is
  26 # sufficient to check only distributed man pages.
  27 #
  28 # Idea of this whole shenanigan is to allow somebody to check out sources from
  29 # a VCS and build and install them without needing help2man installed.  The
  30 # installed man pages will be bogus in this case.  Typically, this happens
  31 # when developers ask users to try out a fix from VCS; the developers themselves
  32 # will usually have help2man installed (or should install it).
